This image shows the star VB 10 moving across the sky over a period of nine years. Astronomers nabbed a planet circling this star using a method called astrometry -- the first successful application of the method to planet hunting.

This artist's concept shows four of the five planets that orbit 55 Cancri, a star much like our own. The most recently discovered planet, and the fourth out from the star, looms large in the foreground.
